This reverts commit fcad4cc646a23e4e621ec5e8485958ab78d98090. This was wrong is so many ways. * The memcmp was badly used (it should use == 0 to check the data is identical, and not != 0) * There was no boundary checks on the present stream section_data when passing it to memcmp. * The return value should have been TRUE (i.e. we have done all checks, none of them failed, therefore the section has been seen before) * stream->section_data would *always* be NULL if the section had already been processed Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1559 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3421>
